A jury in September agreed with the company and ordered Samsung to pay one billion US dollars (£623 million). Samsung has moved to set the judgment aside.

In its ruling, the appeals court said Apple had failed to show that any of the patent violations it accused Samsung of in regards to the Galaxy would immediately and irreparably hurt its own smartphone sales.

It said Judge Lucy Koh had abused her discretion in granting Apple a preliminary injunction earlier this year.
